I have a wireguard server on my opnsense router. My phone and my wifes phone is permanently connected, doesnt matter if we are on home wifi or not, we just leave it on. Very basic, very stable.

My daily driver is a t450s running Fedora Kinoite. It’s great, all working fine, but browsing is getting a bit heavy on it, and battery life is less than an hour, so it’s mostly used stationary. Thinking of upgrading to a T14 G3.
